How this service works
SEO audits, website security checks, SEO content plans, articles and site fix plans as API endpoints for AI agents. Pay per request in USDC on Base with…
Output
Returns a JSON object with: alive (true/false), reason code (ok, http_404, dns_not_found, timeout, etc.), the original URL, final URL, final domain, final HTTP status, redirect count, full redirect chain (each hop's URL and status), TLS certificate info (validity, issuer, days left), response time in milliseconds, content type, content length, flags (e.g. cross_domain_redirect, https_downgrade, shortened_link), and whether the link was a URL shortener.
Example use cases
Verify link before campaign launch
“Before we send out the email blast, check that https://bit.ly/promo2024 is alive and show me every redirect hop and the final landing page URL — I need to make sure it doesn't bounce to a 404.”
Detect broken link in docs
“One of our docs links seems broken — can you check https://docs.example.com/old-guide and tell me if it's alive, why it fails if not, and what the final URL is after any redirects?”
Security check on suspicious URL
“Someone sent me this link: https://t.co/xyz99 — can you resolve it and tell me the real destination domain, whether there are any cross-domain redirects or HTTPS downgrades, and if it looks safe to visit?”
Technical details
Endpoint
GEThttps://shop.lordevo.com/api/quick/link-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single URL checked with full redirect resolution, TLS details, and structured flag detection (shortener, HTTPS downgrade, cross-domain). It is preferable over a raw HTTP call when you need a browser-like redirect traversal with structured output. Prefer the sibling batch endpoint (Lordevo Batch link check) when checking multiple URLs at once. Prefer this single-URL endpoint for real-time, per-link decisions where latency matters and detailed per-hop data is needed.
Side effects
- DNS resolution failure returns alive:false with reason dns_not_found
- Timeout after redirect chain returns alive:false with reason timeout
- HTTP 404 at final destination returns alive:false with reason http_404
- Exceeding 10 redirects may truncate chain and return partial results
- Missing or invalid url query parameter returns an error
- Private/internal URLs may fail to resolve from the service's network
- Some servers block HEAD requests; service falls back to GET automatically
